Major hepatectomy in Bismuth types I and II hilar cholangiocarcinoma

Abstract Background Historically, hilar bile duct resection (HBDR) has been regarded as the choice of treatment for Bismuth types I and II hilar cholangiocarcinoma (HCCA). The present study aimed to evaluate the advantages of major liver resection (MLR) in the treatment of patients with Bismuth types I and II HCCA when compared with HBDR. Materials and methods Between January 2005 and September 2012, in total, 52 patients with Bismuth types I and II HCCA who underwent HBDR alone or MLR were included for retrospective analysis. The intraoperative outcomes, postoperative complications, and oncological outcomes including recurrence and overall or disease-free survival rate were compared. Results The MLR group had significantly higher curative resection rates compared with the HBDR group (95% versus 62.5%, P = 0.021) and lower tumor recurrence (28% versus 63%, P = 0.049), albeit with longer operating time (395.5 ± 112.7 versus 270.9 ± 98.8, P
